Description

Method and device for constructing multi-point coordinated transmission cell cooperation set

Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and apparatus for constructing a coordinated multi-point transmission (CoMP) cell.

Background technique

The existing LTE-Advanced (LTE Evolution) system uses the same frequency networking technology, and the OFDM (Orthogonal Frequency Division Multiple Access) access mode enables the information of users in the cell to be carried on different subcarriers that are orthogonal to each other. Thereby, multiple access interference between users in the cell is avoided, but inter-cell interference (ICI, Inter-Cell Interference) cannot be suppressed. For the cell edge users, the useful signal strength is small, and the interference signal strength from the neighboring cells is large, so that the edge users cannot get good service. Therefore, small-area interference suppression has become an urgent problem in LTE-Advanced systems.

In order to solve this problem, the industry has proposed various technologies, such as power control, flexible frequency reuse, and random interference cancellation. These technologies all increase edge user throughput, but at the expense of overall cell throughput. In this case, Multipoint Collaborative Transfer (CoMP) technology was proposed.

The CoMP technology is a technology for realizing data transmission by utilizing cooperation between a plurality of geographically separated transmission points, where multiple transmission points refer to different network side access nodes, including but not limited to an evolved base station (eNB) or Wireless relay node. The principle of this technology is that multiple base stations cooperatively provide services to edge users by means of distributed network MIMO, thereby effectively improving the effective signal to interference and noise ratio of edge users, as shown in FIG. The premise of using this technology is to construct a suitable CoMP cell cooperative set, namely CoMP cluster.

Constructing a CoMP cooperating set means selecting a plurality of base stations from a plurality of adjacent base stations to form a cluster. There are three main methods for constructing CoMP cooperative sets. One is to form CoMP clusters in a fixed manner. The feature is that a fixed number of base stations are selected to form clusters. All users correspond to the same cooperative cluster. The method is simple, but the system performance is limited. The other is to form a CoMP cluster centered on the user, which can form clusters according to the needs of users, and the performance improvement is relatively large, but the complexity is too high; The fixed CoMP cluster is formed with the user as the center to form the final CoMP cluster. The feature is to predetermine a large collaboration set (pre-collection set), and then dynamically select the participating base stations in the pre-collaboration set according to user requirements. A compromise between the two types of methods leads to a compromise between performance and complexity. The third type of method is a more discussed method in the industry.

Most of the existing methods dynamically select the participating base stations in the pre-cooperative cluster according to the needs of each user, or the method of selecting the final cooperative cluster by using the parameter threshold or using a complicated algorithm to select the final The method of collaborative clustering. However, as the scale of the network expands, these existing methods still bring about a dramatic increase in complexity, but the performance may not be correspondingly improved.

As shown in FIG. 2, the method for constructing a CoMP cell cooperation set in this embodiment includes the following steps: Step 210: Determine a terminal to be subjected to a CoMP operation, and generate a CoMP terminal list; the CoMP terminal list is determined according to a quality of service parameter, specifically The following method is used to determine: the mobile terminal that needs to perform CoMP operation is selected from the preset network area according to the quality of service parameter, and the mobile terminals that need to perform CoMP operation are sorted according to the quality of service parameter, and the foregoing CoMP terminal list is obtained.

A mobile terminal that needs to perform CoMP operation is usually a terminal that is more interfered at the edge of the cell. The service quality parameter used to select the mobile terminal that needs to perform CoMP operation includes one or more of the following parameters: Signal Interference Noise Ratio (SINR), Reference Signal Receive Quality (RSRQ) ), Reference Signal Receive Power (RSRP), and a function that includes one or more of the above parameters. After selecting the quality of service parameter used as the selection terminal, setting the threshold of the quality of service parameter, comparing the measured value of the quality of service parameter of all mobile terminals in the preset network area with the threshold value, generally, if measuring If the value is lower than the threshold, the quality of the user terminal is considered to be poor, and the CoMP operation is required. All user terminals that need to perform CoMP operations are sorted according to the quality of service, and the terminal with the worst service quality is ranked first (ie, according to The size of the measured values is sorted, for example, the terminal with the lowest measured value is ranked first, and a list of CoMP terminals is obtained. Priority is given to CoMP operations for users with the worst service.

Step 220: Select a terminal from the list of the CoMP terminals.

The terminal with the worst quality of service is preferentially selected, and the selected terminal may be referred to as a lord.

Step 230: If using a positioning technology to obtain an adjacent terminal within a preset range around the selected terminal The information of the end is selected by the base station to which the neighboring terminal belongs to form the first CoMP cell cooperation set, and the selected terminal and the neighboring terminal to be subjected to the CoMP operation share the first CoMP cell cooperation set.

If it is determined that there is no neighboring terminal within the preset range around the terminal, the positioning technology is used to obtain information (for example, a base station identifier) of one or more base stations within a preset range around the selected terminal, and the selected terminal is selected. The one or more base stations in the range constitute a second CoMP cell of the selected terminal, and the base station with a relatively small load is entered into the cooperation set. The method includes: selecting a base station in which the load rate of all the neighboring terminals belongs to be smaller than a preset first threshold to form the first CoMP cell cooperation set.

The operations of the above steps 220-230 are continued to be repeated for the terminals in the CoMP terminal list until all the terminals in the CoMP terminal list have constructed the CoMP cell cooperation set.

After the CoMP cell cooperation set of the selected terminal is formed, the selected terminal performs a CoMP operation, that is, the base station to which the selected terminal belongs and the base station in the CoMP cell cooperation set cooperate to transmit data to the selected terminal. Optionally, the quality of service of all the terminals performing CoMP operations is periodically reviewed to determine whether to update the CoMP cell cooperation set of the terminal. If the measured value of the parameter representing the quality of service is lower than the set threshold, step 230 is repeatedly performed on the terminal to update the CoMP cell cooperation set of the terminal.

Specifically, the method includes: dividing a geographic area (such as a city center commercial area, a town, and the like) according to requirements, and using all network access points such as base stations in the area as one large Pre-collaboration set C. ;

For C. All terminals U _NonCoMP =, u _NonCoMP ” (excluding terminals that have been determined to perform CoMP operations) calculate the signal-to-interference ratio V o , and the threshold value is 57NR_ 73⁄4r^ ₀ W. In comparison, all terminals that are less than the threshold are added to the list of pre-CoMP operating terminals.

Step 420: Determine a priority CoMP terminal list (ie, a list of CoMP terminals in Embodiment 1);
